New Post: Torn Paper Edge Effect

Hoping somone can help me. I am trying to translate this bit of code found here for the torn paper edge effect. I don't quite grasp the example code they have but am hoping someone might be able to translate this for me into C#

      \( +clone -alpha extract -virtual-pixel black \
         -spread 10 -blur 0x3 -threshold 50% -spread 1 -blur 0x.7 \) \
      -alpha off -compose Copy_Opacity -composite \
      -gravity SouthEast -chop 10x10   torn_paper_corner.png

I have tried doing a masking layer but since the aspect ratio of the final image varies so much it is less than ideal.
